Chances are, they are the drums. I was a little too rough in removing my
drums to inspect the shoes one time.
After that I had a pulsating pedal. I have since than learned how easy it is
to warp the drums.
I now use a small grinder to open up the hub area slightly on the drum
before installing to help in future removal.

Several things here:
First, we all know Lord Bentley says that to inspect the shoes we are to undo
that big-assed axle nut so that we can remove the drum and shoe as a unit.
Sure!  Try to tell that one to Ralph or Rick when the are doing my state
inspection.  I even had to fight with them not to lift the thing by centering
a floor jack on the oil sump.  One thing they did demonstrate which seems to
work without too much harm is to pop off the drum by giving it a sharp INWARD
blow on the OD with a ball peen hammer.

Secondly, if the drums are cut the shoes have to be radiused to match or
there will be rather little shoe to drum contact.  Don't count on them
wearing in as they are used.  I installed new shoes with cut drums once and
after 30Kmi or so, the contact area still did not cover more than about 1/3
of the shoe.  Where I live, the problem is finding a brake shop to radius the
shoes.  It seems with the warnings and regulations regarding exposure to
asbestos, most do not want to piss with it anymore.

Lastly, I think using a grinder on the center hole of the drum is a risky
practice.  That hole is a close fit with the shoulder on the hub to
accurately center the drum.  Cleaning it up with some 180 grit AO cloth or a
maroon-colored Scotchbrite pad then a careful application of Never-Sieze is
all that I have found it needed.
